Re: [libvirt] [PATCH 07/26] virsh: Resolve Coverity DEADCODE

Since 0766783abbe8bbc9ea686c2c3149f4c0ac139e19 Coverity complains that the EDIT_FREE definition results in DEADCODE. As it turns out with the change to use the EDIT_FREE macro the call to vir*Free() wouldn't be necessary nor would it happen... Prior code to above commitid would : vir*Ptr foo = NULL; ... foo = vir*GetXMLDesc() ... vir*Free(foo); foo = vir*DefineXML() ... And thus the free was needed. With the change to use EDIT_FREE the same code changed to: vir*Ptr foo = NULL; vir*Ptr foo_edited = NULL; ... foo = vir*GetXMLDesc() ... if (foo_edited) vir*Free(foo_edited); foo_edited = vir*DefineXML() ... However, foo_edited could never be set in the code path - even with all the goto's since the only way for it to be set is if vir*DefineXML() succeeds in which case the code to allow a retry (and thus all the goto's) never leaves foo_edited set All error paths lead to "cleanup:" which causes both foo and foo_edited to call the respective vir*Free() routines if set.
